The-forni 'of the invention shown in F igures 1 to 5 inclusive isadapted to be employed with a paring knife of the usualiorm includingablade 5 provided with a 'handle 64 and having oneofits longitudinalv`edges sharpened Vto provide acutting edge v7.y The guard for `theblade lin this-form; comprises `a* rectangular blade 'stamped from*sheet metall and provided with a central opening 8 of substantiallyrectangular' form so'that no` Y a frame is lett consisting of endmembers 9 and 10 and side or longitudinal gage or guard members 1 and12. rEhe end members 9 and 10 are provided with extensions 13, andprojecting laterally from each extension is a relatively short tongue 14which projects beyond the side member 127 and a longer tongue 15 whichprojects beyond the side member 11, these tongues 14 and 15 being toprovide spring clips for Agripping reception of the blade 5 whereby tneguard is held in place upon the blade, the tongues 15 being arranged atone side of the same so asto receive'the blade and hold the latter asuiiicient distance trom the inner edge of the side member 11 as to thenadapt the device for slicing, while the tongues 14 are disposed at theopposite side of same for the reception of the knife blade whereby thecutting edge of the latter is held closer to the inner edge of the sidemember 12 whereby the device is adapted for paring. Thus, when thedevice is desired to be used for the slicing of vegetables or the like,a knife blade 5 is clipped under the spring tongue 15 as shown by fulllines in Figure 3, Whereby the edge of the blade is held a sufficientdistance from the side frame member or bar 11 for this purpose. On theother hand, if a thin'paring is to be removed, the blade may bereversibly positioned beneath the clips or spring` tongues 14 asVindicated by dotted lines in Figure 3 in which position the edge of theblade is located closer to the bar 12. It will be understood that thecutting edge of the blade comes in contact with the fold ot the clips 14and 15 and thus gage the distance at which said'edge is placed relativeto the adjacent edge of the operative side guardV member or bar.

In the form of the invention illustrated in Figures 6 and 7, the deviceembodies the same elements. designated by the same referf encecharacters, the difference being that the clips 14and 15 Varebentinwardly between their ends asat 19 so that the tree end portions ofthe saine are directed out- Wardly as at 2O tor permitting the knifeblade to be morereadily inserted under said clips, and-the side members9 and 10 are bent to dispose the guard members 11 and 12 in obliqueposition instead of bending the guardmembers themselves as describedwith respect to the form of invention shown in Figure 1. rlhis isclearly shown by the end elevational view of Figure 7. i

The construction in Figures 8 and -9 is substantially with theconstruction shown in Figures 6 and 7 except that the guard Y membersare reversely bent relative to the direction of bending of the same inFigure 7 so that the device may be conveniently employed by a lefthanded person.

ln the construction shown in Figures 1,V 6 and 8, the members 11 and 12are directed laterally in opposite ldirection so that the clips 14 and15 are ydisposed at opposite sides of the members 9 and 10, but as shownin Figure 10, the Vguard members 11 and 12 may be directed laterally inthe same direc-. Vtion so that the clips 14 and 15 may be bent in thesame direction with respect to each other or in the opposite directionto the bending of the members 11 and 12, thus enabling the knife` bladeto lie at they same side of the device when cooperating with veither oneof the guard members 11 and 12; The only difference is that the clips 14and 15 will be of lesser length and folded at a point nearer to theguard members 11V and 12. rlhe knife blade Will simply be reversed fromone side to the other for cooperating with the desired one of the guardmembers 11 and 12 as Will be apparent.

The construction shown in Figures 12 and 13 is substantially identicalwith that shown in Figures 10 and 11 with the guard member omitted sothat, in this form, the device is adapted for only one operation, eitherparing or slicing, vdepending upon the distance at which the knife edgeis spaced from the guard member 11 when said knife has its bladecooperatively arranged with respect ion to the clips 14 and 15.Obviously, the clips in this form will be lcomposed of three.

`nieces. In this form the guard member 11 is disposed as is the casewithv the form in Figures 6 and 7 while the guard member 12V extendsstraight out. j y Y The form of the invention shown in F ig-` ures 16andV 17 -is substantially the same `as that shown in Figures 12 and 13except that the clips 14 and 15 are bent laterally and rearwardly inopposite directionsfrom 4the same edge of the extension 13 and the guardmember 11 is directed laterally at an angle instead of straightoutwardly as in Figure 13, the extension 13 being preferably made longerso as to dispose the clips 14 and 15 in different transverse planes.

1n Figures 18 and 19 the extension 13 is provided with a singlecooperating pair of clips 14 disposed at'the same side of the .Y frameand integrally connected with the single guard member 12,'the extensions13. be-

ing integrally connected a reinforcing strip portion 21 upon whichltheblade of` the knife may rest for insuringy rigidity.

Ihe form of the invention illustrated in -Figures 20 and 21 isessentially the same as the device-'shown in Figures v8 and 9 with theguard member 12 and clips 15 omitted soV that the device will be adaptedfor only one operation, either that of slicing or paring as ispredetermined. Y

In the form of the invention shown in Figures 22 to 24 inclusive thevVguard member 11 is formed separate from the eXtensions 13 and clips 14and 15', and the guard member 11 consists of a straight strip of metalwith the clips 14 and 15 and eXtensions 13 riveted together at theirends to the ends of the guard member 11 as at 22, the

. extensions 18 lying between theclips 14:

and 15 at each end and said clips and ex- Y tensions extending laterallyfrom the guard 11 in the same direction for clipping of the knife bladethere beneath as will be apparent. With this form of the inventioninexpensive forms of dies may be employed for stamping of the separateparts and the latter may be quickly and effectivelyunited in anassembling operation.

There has thus been provided simple and efficient forms of devices ofthe kind de- Y scribed and yforthe purpose specified, the use V'thespirit and scope of claimed.

and advantages of which will be readily'apparent to those skilled in theartfrom the foregoing description.

While the form of the invention herein shown and described is what isbelieved to be the preferred embodiment thereof, it is nevertheless tobe understood that various forms, modifications and arrangement of partsmay be made without departing from the invention as What I claim ist 1.In a paring and slicing knife, a guard comprising a metallic platehaving an opening therethrough whereby a guard frame is formedcomprising endv and` side members, said side members being benttransversely in opposite directions, and means integral with said. platefor detachably holding said frame y i uponthe blade of a knifel forpresenting the edge of the lattertoward eitherone of said side members,said means comprising a pair of clips of said metallic plate, the clipsupon v one lside of said platev being nearer the edge n of therbladethan the clips upon the opposite side of the plate, said pairs ofclips'being transversely curved in opposite directions."

2, In a paring and slicing knife, a guard comprising a metallicrectangular framel loa 4having Yside guides and end bars, said sideguides being bent to extend at angles to the end bars and end clips ateach side of the frame reversely bent at opposite sides of` `the.

frame and lying Within theeXtreme diam@` ter thereof for attaching theguard to a knife blade. L A

'3. Ina paring and slicing knife, a guard comprising a metallicrectangular frame having'side guides andend bars, with at least one ofthe side guides extending at an etr angle to the end bars, and end clipsat each comprising a metallic rectangular frame having side guides andend bars,qwith' the side guides respectively bent above .and below theend bars,`and end clipsateach side of the frame reversely lbent atopposite'sides thereof andlyingwithin the extremediameter of the framefor attaching the guard to Y a'fknife blade.
